Verify the following: (a) 18 x [7 + (–3)] = [18 x 7] + [18 x (–3)] (b) (–21) x [(–4) + (–6)] = [(–21) x (-4)] + [(–21) x (–6)]
Share
(a) 18 x [7 + (–3)] = [18 x 7] + [18 x (–3)]
⇒ 18 X 4 = 126+(-54)
⇒ 72 = 72
⇒ L.H.S = R.H.S
Hence verified.
(b) (–21) x [(–4) + (–6)] = [(–21) x (-4)] + [(–21) x (–6)]
⇒ (–21) x (-10) = 84 + 126
⇒ 210 = 210
⇒ L.H.S = R.H.S
Hence verified.
